Functional Devices RIBXGTF Sensor

The Functional Devices RIBXGTF is a high-performance split-core current sensor engineered for precise AC current monitoring in commercial and industrial HVACR environments. Designed to facilitate real-time fan and motor status feedback, this sensor features a fixed threshold of 0.75 Amps, ensuring reliable operation for detecting belt breaks or motor failures. The split-core design allows for non-intrusive installation, enabling technicians to snap the device over existing conductors without disconnecting high-voltage wiring. This unit operates as a solid-state switch—specifically an SPST (Single Pole Single Throw) configuration—capable of switching up to 30 Vac/dc at 0.4 Amps. Its high-induction permanent magnet ensures accurate sensing across a 0.75-150 Amp range. For contractors managing building automation systems (BAS), the RIBXGTF provides a rugged solution for load trending and proof of flow, maintaining high reliability in demanding electrical cabinets.

Key Benefits

• Reduced Installation Time: The split-core housing eliminates the need to cut or rewire power lines, making it ideal for retrofitting current monitoring sensors.
• Broad Operating Range: Monitors induction motors and resistive loads from 0.75A to 150A, providing versatile compatibility across various HVACR applications.
• Compact Footprint: Designed to fit within tight junction boxes and motor control centers without obstructing other electrical components.
• Self-Powered Operation: Draws power directly from the induced current of the monitored line, removing the need for an external power supply.

Common Questions

What is the maximum voltage this sensor can handle on the monitored line?
The RIBXGTF is rated for use on monitored lines up to 600 Vac, providing compatibility with standard 208V, 240V, and 480V motor circuits.

Does this unit require a minimum load to function?
Yes, as a fixed threshold sensor, it requires a minimum of 0.75 Amps on the primary conductor to close the SPST output.

Can this sensor be used for variable frequency drive (VFD) applications?
While it can monitor circuits downstream of a VFD, it is optimized for constant volume fans and pumps. For accurate VFD status monitoring, ensure the operating frequency remains within the device's rated range of 50-60 Hz.
